The microstructures, of which a typical atom probe reconstruction is shown in Figure 1, from samples linearly cooled at different cooling rates were examined and compared. The / ´ Experiments were performed inside a home-made ultrahigh-vacuum atom probe chamber with a base pressure of 5 × 10 −10 mbar and a close loop cryostat cooling of the sample to 50 K. The aluminum tip was electrochemically etched from a 0.25-mm-diameter aluminum wire. Indeed, these characteristics influence austenite stability at room temperature after cooling and are therefore at the origin of potential TRIP effects under mechanical loading. Atom probe tomography analyses and Thermo-Calc/DICTRA calculations were used to understand how austenite forms during 1 °C/s heating of a 0.2 wt% C high-formability steel. Atom probe tomography (APT) combined with electron back scatter diffraction and transmission electronic microscopy (TEM) is utilized to characterize the nature of copper precipitation during Atom probe tomography reconstructed three-dimensional images of the experimental steel cooled slowly from full austenite phase at a rate of 0.1 °C/s.

Investigating alternative cooling mechanisms is an active field of research . Although squeezing the quantum noise on an atomic source is difficult and must be coupled with low losses and high quantum efficiency detection if it is to be useful for metrology, there have been some exciting advances in recent years, at least for small samples of Atom Probe tomography (APT) has shown, that it is able to deliver these information on the nano-scale. In our days APT is strongly bounded to the usage of state of the art dual beam microscopes. The sum of both maschines is capable to deliver astonishing results, but sometimes limited in its possibilities by their seperation.

In our work, a Local Electrode Atom Probe 3000 (LEAP) was used to characterize the microstructural evolution of pearlitic steel. Teletype for Atom. Great things happen when developers work together—from teaching and sharing knowledge to building better software. Teletype for Atom makes collaborating on code just as easy as it is to code alone, right from your editor. Atom Probe Tomography Library. We have made available a small atom probe C++ library, called libatomprobe, which is available for download.
